TURBINE AGGREGATE Russian patent published in 2014 - IPC F25B11/02 F01D25/12

Abstract RU 2520763 C2

FIELD: engines and pumps.

SUBSTANCE: invention refers to power engineering. A turbine aggregate comprises a body with a shaft supported by bearings. At least one expander impeller is fixed on the shaft. The bearings are dry ones and are made of polymer composites. The expander impeller and the shaft have canals. The formed canals connect the flow part of the expander impeller with gaps formed by the shaft and bearings.

EFFECT: simplified design and reduced size weight-and-dimensional characteristics of the turbine aggregate.
